connection string

ciao

ho problemi con la connection string di un sito web.
Uso la Page per configurarla...........
sugli altri pannelli di controllo usavo il web config, mentre in questa volevo inserire direttamente sulla page il la connection string.......

errorre riscontrato:
[code]
Object reference not set to an instance of an object.

il codice che non funziona:

objdb.ConnectionString = ConfigurationManager.ConnectionStrings("Data Source=WIN3854\SQLEXPRESS,1433;Initial Catalog=MyArtistic;Persist Security Info=True;User ID=MArtistic;password=Arte422").ConnectionString

Dove ho sbagliato ??

Se ho capito bene la connessione non si trova nel web.config ma allora perchè stai usando la classe ConfigurationManager?
Quest'ultima ti permette di accedere ai file web.config, ti basta valorizzare una variabile di tipo stringa con la tua connessione.
